Structure and properties of hydrophilic polymers and their gels. VI. Equilibrium deformation behaviour of polyethyleneglycol methacrylate and polydiethyleneglycol methacrylate networks prepared in the presence of a diluent and swollen with water

Water diffusion in hydroxyethyl methacrylate (HEMA)-based hydrogels formed by γ-radiolysis

“…In the case of tetraEGDMA the diffusion coef®cient appears to increase slightly at the higher crosslinker concentrations, which may be due to the larger spacer group in this comonomer. As pointed out previously, other workers 8,9 have also found little effect of mEGDMA on the sorption properties of poly(HEMA), at low added crosslinker contents.…”

“…Chen 6 has suggested that below about 0.4% mEGDMA a pore mechanism for diffusion is dominant, but above this composition the diffusion mechanism changes. However, other workers 8,9 have found that water uptake by poly(HEMA) is relatively insensitive to low degrees of crosslinking by mEGDMA, which suggests that the effective level of crosslinking in the gels is not essentially changed at low crosslinker contents.…”

Swelling and network parameters of high oil‐absorptive network based on 1‐octene and isodecyl acrylate copolymers

“…This agrees with the finding that the crosslinking decreases with decreasing content of diluent. 35 It was also observed that the ␤ values for crosslinking of 1-octene/isodecyl acrylate by EGDA and EGDMA crosslinkers via chemical initiation and electron-beam irradiation are 0.2954, 0.5235, 0.1054, and 0.14, respectively. This finding reveals that EGDMA is more efficient than EGDA for crosslinking of 1-octene/isodecyl copolymers.…”

Synthetic Hydrogels for Biomedical Applications

“…The swelling of P-HEMA gels has also been studied with respect to the fundamental equations describing the swelling of crosslinked networks (32).…”

“…Many of these are listed in Table IV. Fundamental studies on the healing of disks of P-HEMA subcutaneously implanted in rats and pigs were performed primarily by researchers at the Institute of Macromolecular Chemistry, Prague (31)(32)(33)(34)(35)(36). Homogeneous P-HEMA and heterogeneous P-HEMA materials with varying degrees of porosity were examined.…”
